Dow 30 firms shows declining tax burden as a share of profits

The Washington Post reports:

A Washington Post analysis of data from S&P Capital IQ, a research firm, found that in the late 1960s and early 1970s, companies listed on the current Dow 30 routinely cited U.S. federal tax expenses that were 25 to 50 percent of their worldwide profits. Now, most are reporting less than half that share.
